You need to use the BackgroundWorker for your long running task and use Dispatcher to update UI in between

 //create background worker
 BackgroundWorker worker = new BackgroundWorker();
 //assign it work
 worker.DoWork += new DoWorkEventHandler(worker_DoWork);
 //start work
 worker.RunWorkerAsync();


//this work will be done in background
void worker_DoWork(object sender, DoWorkEventArgs e)
{
    SET initial = 0;
    SET maxData = 1000
    DO UNTIL initial <1000
   CREATE db query "INSERT INTO (col1,col2,col3) VALUES(value1,value2,value3);"

   //in between your work do this to update label
   label.Dispatcher.Invoke(System.Windows.Threading.DispatcherPriority.Normal,new Action(delegate()
        {
         Label.Content = "SomeValue";
        }
        ));
   END DO
  }
